Why from the flu still die

• Why is a flu shot still die

Every flu season - the off season. We fly into space, exploring the oceans, trying to find the secret of perpetual motion and doing other nonsense, as if oblivious to the fact that it is not able to cope with the virus, which is a sign of humanity for several hundred years. Every year from influenza and its impact on people die and medicine simply unable to help. Why is this happening? Let's see how completely banal infection continues to be deadly.

Age

For very old and very young people, the flu is deadly. The immune system and an eight-eighty-year, for example, a person simply does not have enough resources to withstand the constantly mutating virus. This does not mean that people do not die, and in the prime of life, but to save the 20-year-old is more than chances of the flu.

pneumonia

Inflammation begins because the white blood cells of various types, which are, in fact, engaged in the destruction of the virus in your blood. Inflammation - an immune response to all kinds of problems, from viruses and bacteria to physical injuries. This is not a problem for short-term infections, but the situation is different with the flu. For example, a tumor in the lung can prevent oxygen from penetrating into the blood vessels. Gradually the light just begin to break down from lack of oxygen. Is due to the influenza virus lung tumor can kill very quickly. Sometimes it is missing just two to three days, though everything is quite unexpected for the patient.

Sepsis

And inflammation is not limited to the lungs. Severe infection will lead to reactions at the level of the body and cause septicemia: Essentially, your immune system begins to respond so strongly that it will suppress the inflammation caused by the work of many vital organs. Are particularly vulnerable to such an attack the heart and brain. These bodies are not able to recover, as the kidneys and liver, in addition, inflammation of the brain is very fast and 75% leads to death.

Secondary infection

The flu virus if the gate opens the way infections. Pick up something in addition to the virus - simple. Most often it develops pneumonia, dangerous in itself. This is because the immune system does not have the resources to fight the flu at the same time and keep a barrier against bacteria, which each of us is more than enough. The bacteria begin to multiply uncontrollably, developed the so-called secondary infection. If it affects the lungs, pneumonia can not be avoided.
